Bottle stop remover

ABSTRACT

The present invention relates to devices and methods for removing a stop from a bottle. In certain embodiments of the present invention, a stabilizer is provided to prevent the stop from being pushed into the bottle and insert members are provided for removing the stop without the outside of the stop adhering to the inner wall of the bottle. Such embodiments allow, among other things, removal of the stop from the bottle without destruction or partial destruction of the stop, as is sometimes the case with conventional corkscrews, yet without the risk of pushing the stop into the bottle as is sometimes the case with non-corkscrew bottle stop removers.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 11/374,404 filed Mar. 13, 2006, now U.S. Pat. No. 7,237,455 which claims the benefit of U.S. Provisional application Ser. No. 60/696,774 filed Jul. 5, 2005, the contents of which are incorporated herein by reference.

FIELD OF INVENTION

This invention relates generally to devices and methods for removing a stop from a bottle.

BACKGROUND OF THE INVENTION

Some bottles, such as wine bottles, have a stop or cork like structure to retain the bottle's contents inside the bottle. In bottles with a stop, the stop is generally positioned with a friction or interference fit between the inner walls of the bottle opening to block the opening and prevent the contents from spilling, evaporating, spoiling or becoming contaminated. Often a stop, particularly a cork, cannot be easily removed from the bottle without a tool.

One tool used to remove stops from bottles is a corkscrew with a handle or lever. To remove the stop, the corkscrew is rotated into the stop and the handle is pulled or the lever is used to draw the corkscrew out of the bottle along with the stop. Using a corkscrew on older stops and corks, however, may result in the stop or cork being severed, damaged, or the middle of the stop or cork being pulled out of the bottle and the outer part of the stop or cork adhering to the inner wall of the bottle opening. Cork bits in the contents and other effects of such stop damage can be undesirable.

Another device used to remove stops or corks from bottles is a device commonly referred to as an “ah-so.” The ah-so has two elements, one typically longer than the other, connected to a handle. Using the handle, the longer element is inserted between the stop and bottle opening inner wall. As the shorter element is then similarly inserted, the handle is rocked and a downward force is applied, first on one element and then on the other, until both of the elements are substantially along the length of the stop. The elements are then twisted and pulled upward using the handle and the stop is removed by and with the elements. Conventional “ah-so” devices, however, may sometimes push the stop or cork, particularly older or fragile corks, into the bottle when the elements are being inserted.

Another device used to remove stops from bottles is a hollow needle that is punched through the stop and air is inserted through the hollow needle. The increasing air pressure in the bottle pushes the stop out of the bottle opening. The stop, however, may be pushed into the bottle in the effort to punch the needle through the stop. Additionally, some find that the liquid contents may be adversely affected by the increased pressure used to remove the cork.

Therefore, a need exists for a device for removing bottle stops that is less likely to, among other things, sever or damage the stop, leave the outer part of the stop adhering to the side of the bottle opening, or push the stop into the bottle.

SUMMARY OF THE INVENTION

The present invention includes new devices and methods for removing stops from bottles. Such devices and methods allow removal of the entire stop, even if the stop is old and fragile, and with little risk that the stop might be pushed into the bottle. Various aspects and embodiments of the present invention provide a stabilizer for gaining purchase or gaining grip within the stop, together with an integrated or connected element that is preferably greater in at least one dimension than the inner diameter of the bottle opening for preventing the stop from being pushed into the bottle. Insert members may also be provided and may be inserted between the stop and the inner wall of the bottle. In some embodiments of the present invention, a handle may be connected directly to the insert members and/or connected detachably to the stabilizer for applying a force to insert the stabilizer and/or to insert the insert members and/or to extract the stop.

In particular embodiments of the invention, the stabilizer may prevent the stop from being pushed into the bottle when the insert members are inserted. The insert members may extract the stop without leaving the outside of the stop remaining on the inner wall of the bottle opening.

In certain embodiments of the present invention, a portion of the stabilizer is helically shaped, similar to a corkscrew, and may be essentially round and/or oval in cross section. In particularly preferred embodiments, the stabilizer is not used to extract the stop. Instead, the stabilizer prevents the stop from being pushed into the bottle. The stabilizer cross element may be an elongated structure with a length longer than the inner diameter of the bottle opening in order to prevent the stop from being pushed into the bottle by the insert members. In preferred embodiments of the present invention, the cross element may rest against the top of the bottle and does not interfere with the insert members being inserted between the stop and inner wall of the bottle opening. Furthermore, the cross element may be smaller than the handle of a conventional corkscrew.

A particular method of the present invention for removing a stop from a bottle includes providing a stabilizer with a first portion for gaining purchase on a stop in a bottle and a second portion with at least one dimension greater than the inner diameter of the bottle opening. A separate device such as a prong may also be provided having a first portion that includes insert members for inserting between the stop and the inner wall of the bottle opening and a second portion with a handle to apply a force to insert the insert members and/or to extract the stop from the bottle. The stabilizer may be inserted into the stop, with a first portion gaining purchase and the prong insert members may then be inserted between the stop and the bottle inner wall. The stabilizer is preferably inserted until the second portion rests against the top of the bottle opening. The stabilizer preferably stabilizes the stop and prevents the stop from being pushed into the bottle when the insert members are inserted. The stop may then be removed by using the prong handle to retract the insert members, stabilizer, and the stop from the bottle opening.

An advantage of certain aspects and embodiments of the present invention is to provide a bottle stop remover that does not push the stop into the bottle.

A further advantage of certain aspects and embodiments of the present invention is to provide a bottle stop remover that removes the whole stop and does not leave part of the cork adhering to the bottle opening inner wall.

A still further advantage of certain aspects and embodiments of the present invention is to provide devices and methods for removing a bottle stop without causing the stop to be severed or damaged in a way that adversely affects the liquid contained in the bottle.

Alternatively, a handle may be detachably, or otherwise, connected to the stabilizer 1100 for inserting the stabilizer into the cork. The stop and stabilizer 1100 may then be removed using a separate device.

FIGS. 8-11 are a sequence of illustrations that show a bottle stop remover 700 according to one embodiment of the present invention (FIGS. 1 and 2) removing a stop 701 from a bottle 703. As shown in FIG. 8, a stabilizer 710 is provided with a first helical shaped portion 712 and a second cross-element portion 714. The helically shaped portion 712 may include a sharp-tipped end (not shown) and a body portion 716 for gaining purchase on the stop 701. Alternatively, the stabilizer 710 may be of any configuration to gain purchase on the stop 701. The cross element portion 714 includes an elongated portion 720 that is longer than the inner diameter of the bottle opening 705. The elongated portion 720 includes end openings 722, 724, 726 for detachably connecting to a prong 728.

The prong 728 is provided having insert members 730, 732 connected to a handle 734. In some embodiments of the present invention, one insert member 732 is preferably longer than the other insert member 730. As illustrated in FIG. 8, the insert members 730, 732 are inserted in the stabilizer end openings 722, 724, 726 and the stabilizer end is located approximately in the center of the stop 701. The handle 734 may then be used to rotate the prong and thus the stabilizer 710 (here as an example in the clockwise direction) and with a slight force downward with respect to the stop 701 to gain purchase in the stop. The stabilizer 710 is inserted and rotated into the stop until the cross element 714 is at the top of the bottle opening 705, and preferably against the top of the bottle opening 705 as shown in FIG. 9. Alternatively, the stabilizer 710 may be inserted and rotated into the stop manually. The prong 728 is then removed from the stabilizer end openings 722, 724, 726 by pulling upward on the handle 734.

The handle 734 and prong 728 are then rotated, preferably 90 degrees with respect to cross element 714, but may be rotated as desired to allow the insert members 730, 732 to be inserted between the stop 701 and the inner wall of the stop opening 705. Using the handle, the insert members 730, 732 are inserted between the stop 701 and the inner wall of the bottle opening 705 by partially inserting one insert member 732, preferably the longer insert member, pressing down and rocking the insert member 732, as needed, to partially insert it, and then inserting the other insert member 730 and pressing down slightly. Using the handle 734, the insert members 730, 732 may be alternately pressed down, as needed, until the bottom of the handle is located at the top of the bottle opening 705 and the insert members 730, 732 extend along the stop 701, as illustrated in FIG. 10.

In one embodiment, the insert members 730, 732 are preferably attached to the stabilizer 710. The stabilizer 710 is inserted into the stop 701. The insert members 730, 732 are preferably inserted between the stop 701 and the inner wall of the bottle opening 705 without detaching the insert members 730, 732 from the stabilizer 710 and/or rotating the insert members 730, 732.

As illustrated in FIG. 11, the handle 734 may be twisted slightly and pulled upward, thereby removing the insert members 730, 732, stabilizer 710, and stop 701 from the bottle 703. The stop 701, removed from the bottle 703 with the insert members 730, 732, is separated from the stabilizer 710 for reuse by preferably holding the stop to prevent the stop from rotating and rotating the stabilizer 710 counter-clockwise relative to the top of the stop.
